// One-time PayPal setup: creates the product + the recurring billing plans and
// prints the plan IDs to paste into your environment.
//
//   1. Set PAYPAL_CLIENT_ID / PAYPAL_SECRET (and PAYPAL_ENVIRONMENT) in .env.local
//   2. node scripts/paypal-setup-plans.mjs
//   3. Copy the printed PAYPAL_*_PLAN_ID lines into .env.local / production env
//
// Amounts mirror the app's pricing (Pro $29/mo, Landlord $59/mo); yearly is
// billed at 10× monthly (~2 months free). Adjust in the PayPal dashboard if you
// want different annual pricing. Safe to re-run (it creates fresh plans).
